Cyrus tweaks (slow on roundcube)

Hello,
Entropy of 158 is way too low for production servers. And this *MAY* cause weird
slowness without logging any  errors.
You could install "haveged" and configure for max threshold levels on production
servers.
https://packages.debian.org/search?keywords=haveged

Regards.
